| Abstract: | Routine measurement of blood pressure in high risk neonates admitted to the intensive care nursery during a 2 year period resulted in detection of 18 infants with persistent hypotension requiring definitive treatment. The perinatal events in these babies were compared to those in a control group of infants. No single well defined factor responsible for neonatal hypotension could be found in the antenatal period or during labour. However 14 of the 18 babies were asphyxiated at the time of admission compared to 6 of 18 controls (p less than 0.02). Seventeen of 18 babies were preterm. Treatment consisted of maintenance of ventilation, oxygenation and acid-base status, volume expansion when indicated and inotropic agents. Nine of the 18 hypotensive babies died compared to 1 of 18 controls. Failure to respond within a few hours of commencement of treatment indicated poor prognosis. |
